BULLET.

Speccaton of Letters Patent.

Patented Mar. 20, iir.

Application filed March 25, 1916. Serial No. 86,587.

To aZZ whom t may concern:

Be it known that I, O'riro V. KEAN, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful improvements in Bullets, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bullets, and more particularly to small arms bullets of the hard jacketed' type.

It has heretofore been customary, in the ina-inrfacture of such ammunition, to einploy a acket of tough metal drawn to shape and subsequently filled with a lead core. A jacket so made has required successive drawing and annealing operations and difficulties entailing expense have been encountered in insuring a uniform thickness of metal throughout the product.

The primary object of this invention is to provide an improved bullet of the type mentioned which'is capable of expeditious and relatively cheap manufacture.

@ther objects and advantages will he in part noted hereinafter in connection with the following description of a typical embodiment of the invention illustrated in the accompanying drawing, wherein- Figure l is a perspective view of the im proved bullet;

Fig. 2 is an end view;

Fig. 3 is a side view of a section of the jacket; and

Fig. 4 is an end view thereof showing a slightly modified form.

The invention comprises, in general, a bullet having a hardened jacket divided into complementary7 sections formed of stamped metal and held together by insertion of a soft metal core.

Referring more particularly to the drawing, the bullet is provided with a jacket, preferably of a conoidal form, divided longitudinally into two complementary sections l and 2, these sections being arranged relative to each other transversely circumferentially of the bullet. The sections l and 2 are of stamped metal, having smooth eXteriors and intuned longitudinal ribs or flanges 3 which fit together and interlock with the core to retain the sections in position relative to each other.

The core of the bullet is preferably of lead or other readily fusible metal, which is poured into the jacket when the sections of the latter are held together, thereby anchoring the flanges 3 securely together. it is to be noted that the jacket sections are capable of expeditious manufacture from rolled plates of suitable material, usually a nickel copper alloy, such practice permitting of the sections being made integral longitudinally of the bullet for the full length of the jacket, this longitudinal continuity of the sections a lfording a. substantial compressive strength thereof longitudinally, the bullet thereby offering great resistance to mushrooniing. If desired, the inner edges of the flanges 3 of the jacket sections may be roughened or corrugated, as indicated at il in Fig. 3, and further the inner surface of the sections may be scored slightly, as indicated at 5 in Fig. 1i, in order to afford a bet- 'ter gripping surface for the lead core when inserted.

Bullets made, as described, are efficient in service and will not produce the dum-dum effect, the flanges 3 stiening the jacket longitudinally. Furthermore, all the advantageous characteristics of the ordinary jacketed bullet are retained, while the manufacturing and assembling cost thereof is materially reduced.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could he made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting` sense.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. In a bullet, a jacket composed of longi tudinally disposed sections arranged transversely circumferentially of the bullet relative to each other.

2. In a bullet, in combination, a core, and a longitudinally sectional jacket therefor having longitudinally disposed internal stiffening ribs.

3. In a bullet, in combination, a core, and a conoidal jacket therefor composed of sections relatively transversely circumferentially arranged and anchored together by said core. l

4. In a bullet, in combination, a core, a

hard metallic jacket therefor composed of sections relatively transversely circumi'erentially arranged, and longitudinally disposed internal projections on said sections, said core anchoring said sections together.

in a bullet, in combination, a core, a hard metallic jacket therefor composed of sections relatively transversely circumferentially arranged, and longitudinally7 disposed and abutting internal projections on said sections, said core anchoring said sections together.`

6. In a bullet, in combination, a jacket Vcomposed of hard stamped metal Vsections relatively transversely circinnferentially arranged, internal longitudinal iianges on said sections abutting each other respectively. and a filling cooperating with said fianges to anchor said sections together.

7. .in a bullet, in combination, a jacket composed ot hard stamped metal sections relatively transversely circ-innferentially arranged, internal longitudinal flanges on said sections abutting each other respectively, and a filling cooperating with Said flanges to anchor said sections together, portions of the inner face of' said jacket being roughened to securely grip said core.

8. ln a bullet, in combination, a` jacket composed of stamped metal sections respectively integral longitudinally of the bullet for the length of the jacket.

9. In a bullet, in combination, a jacket composed of stamped metal sections respec tively integral longitudinally of the bullet f'or the length Yor" the jacket, and a core, said sections having internal projections adapted to interlock with said core to anchor said sections in position relative to each other.

i0. in a bullet, in combination, a jacket composed of stamped metal sections respectively integral longitudinally of the bullet for the length of the jacket, said sections having internal flanges, the flanges of one section abutting those of another section, and a filling for said jacket with which the said lianges cooperate to anchor said seetions in position relative to each other.

il. In a bullet, in combination, a` jacket composed of stamped metal sections respectively integral longitudinally of the bullet for the length of the jacket, said sections being arranged transversely circumferentially of the bullet relative to each other.

l2. In a bullet, in combination, a core, and a jacket therefor comprising sections rela- 'ively trai'isversely eircnmferentially arranged, and anchored together by said core.

in testimony whereof I affix my signature,

f in the presence of two witnesses.
